COUNTER.

Application filed September 24, 1923. Serial No. 664,492.

To all whom it may concern:

Be it known that I, EDMUND G. STOSICK, a citizen of the United States, and resident of Milwaukee, in the-county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Counters, of

which the following is a description, reference being had to the accompanying drawings, which are apart of this specificatlon.

The invention relates to registers, and more particularly to counters.

One of the objects of this invention Is to improve upon and simplify the counter drive mechanism shown and described 1n United States Letters Patent No. 1,261,081, to Charles P. Wetmore, dated April 2, 1918.

A further'object of the invention is to provide a lock for the resetting mechanism to prevent unauthorized resetting of the counter or tampering with the registration displayed by the counter.

A further object of the invention is to provide a simple, compact and neat design of casing for enclosing the counting wheels.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a front elevation view of a. counter embodying the invention; Fig. 2 is an end view thereof; Fig. 3 is a front elevation view of part of the casing, the cover and one of the number Wheels being shown in vertical section: Fig. 4 is a detail sectional view taken on the line'sl of Fig. 3, part of the number wheel being broken away; Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. 3; Fig. 6 is a detail sectional view taken on the line 66 of Fig. 3: Fig. 7'is a detail horizontal sectional view through one end of the casing to show the locking mechanism; Fig. 8 is a view of the key to operate the locking.

In the drawings the numeral 9 designates the casing formed of a single die casting and 10 a cover therefor. A shaft 11 is journalled in the ends of the casing and is secured against endwise movement relative thereto by a handle 12 and a collar 13, both of which are pinned to the shaft. The turning of the shaft 11 may be effected by the handle for the purpose of resetting the counter as hereinafter described.

A seriesof number wheels 14 are loosely mounted-0n the shaft 11 within the casing and each wheel is provided on its periphery with a series of uniformly spaced numerals O to 9, inclusive. and each wheel 1s formed with an internally serrated rim 15, as shown last number wheel does not have to have this Geneva gear.

Between the several number wheels, gears 19, each having twenty teeth, are loosely mounted on the extended hubs of said wheels. and are provided with spring dogs 20, each fixed thereto at oneend and engaging at the opposite end with the serrated or ratchet rims of said wheels, as shown in Figs. 3 and 5.

A transmission shaft 21 is rotatably mounted in the ends of the casing parallel to the shaft 11 and on this shaft between the number wheels 14 are loosely mounted the transfer pinions 22, each of which works with the Geneva gear of one number wheel and the gear 19 of the adjacent number wheel. 'As shown in Figs. 3 and 5, alternate teeth 28 of each pinion are cut away to clear the rim 17 of the associated number wheel, while the remaining teeth 24 extend com: pletely across the face of the pinion and bear against the rim 17, as shown in Fig. 3, to lock and hold said pinion and gear 19 with which it meshes against turning except when the teeth of the portion 16 engage the pinion. The teeth of the portion 16 project toward the opposite gear 19 beyond the rim 17 and work with both the wide and narrow teeth 23 and 24 of the pinion. With this construction when the first number wheel has been given a complete turn by a step-bystep rotation, the pinion 22 will be rotated to advance the next number wheel one digit, and when said second number wheel has been given a complete turn in the same manner the transfer pinion 22 in mesh therewith will be rotated to advance the next number wheel and in this way successive number wheels are turned to indicate the total number of movements of the machine to which the counter may be connected.

shown in Fig. 4, and move said ratchet wheel .by means of atooth or pawl 27 on a rocker shaft 28 while a pawl 29 loosely mounted 'on the transmission shaft 21 and urged by a spring 30 against the ratchet wheel 25 s adapted to prevent overrunning of sald wheel and is engaged by a locking pin 32, carried by the disk 33 on which the pawl '27 is formed. when the pawl 27 has completedits feeding movement. The disk 33 is driven from the shaft 28 by a pin 33' having a drive fit with the shaft and having its ends disposed in slots in the hub of the disk.

The throw of the pawl 27 is limited in one direction by the engagement of a stop portion 34 on the disk 33 with a fixed stop portion 35 formed-by a part of the casing, and in the other direction by the engagement of a stop portion 36 on the disk 33 with a fixed stop portion37 formed by a part of the casing. With this construction the oscillation or rocking of the shaft 28 by the operative,

connection of the handle 38 thereon with a rotating or. reciprocating part of the machine to which the counter is applied pro- 1 duces a step-by-step rotation of the ratchet wheel 25. The machine moves the shaft28 to accomplish the feeding stroke of the pawl 27 while the return stroke is preferably accomplished by means of a coiled torsion spring 39 secured at one end to said shaft. 28 and at its other to the casing.

With this construction the handle 38 with the shaft 28 is rocked back and forth and the pawl 27 is moved thereby into and out of engagement with the ratchet wheel 25,

- the pawl 27 when moving from the position shown in Fig. 4 to its other extreme position determined by theengagement of stop 36 with portion 37 operating to turn the ratchet wheel 25, which has ten teeth, one tooth' or a tenth of-a revolution, while the tooth of the pawl 29 rides over onev tooth and then moves into locking engagement with the next tooth of said wheel 25 and during the return movement of said shaft the pawl 29 holds the wheel 25 against feeding movement and the pin 32 engages the lower end of the pawl 29 when the pawl 27 returns to the position shown in Fig. 4. The operation above mentioned being repeated, the first number wheel is turned step-by-step, bringing one numeral thereon after another into .view. During the last tenth of every revolution-of each number wheel, as the zero is brought into view through the opening in the casing, the Geneva toothed gear engaging with the teeth of the associated pinion 22 turns said pinion and the gear 19 with which it meshes an interval corresponding to two teethor'a tenth of a revolution, thus carrying the next numeral on the number wheel of the higher denomination into view. As these operations are repeated, every revolution of a number wheel of a lower denomination turns a number wheel of the next Jiigher denomination a tenth of a revolution, as above explained, as long as the machine with which the counter is connected continues to operate.

The casing 9 has an open front and top with recesses 40 in the ends in which-the (IJVCI 10 is fitted, and recesses 41 in which a glass plate 42 is held by the cover 10, the reading of the counter being had through said plate 42.

In order to reset the counter to zero each of the number wheels has a resetting pawl 43 pivotally mounted thereon on the same side as the rim 17 and is urged into enga ement with the shaft 11 by a spring 44, t e hubs of the number wheels being cut away to prevent interference with a longitudinally extending groove 45 into which the ends of the pawls may drop or move when during the turning of the shaft 11 by the handle 12 this groove comes into line with and gears 19 by reason of the pawl and ratchet connections above described between said wheels and said gears and the ratchet wheel 25 as the internally serrated rims of the number wheels slip freely over the outer ends of dogs 20 and 26. During the drivin g of the counter, the pawls 43 slip over the grooved shaft 11.

To prevent unauthorized resetting or tampering with the registered count, I have provided a key-controlled locking mechanism to lock the shaft 11 against rotation, consisting of a locking pin 46 slidably mounted in a bore 47 in a boss at one end of the frame and having an annular groove portion 48 into which the bit 49 of the key 50 fits whereby said pin may be moved longitudinally by the turning of the key. A spring 51 interposed between the inner end of the bore47 and the inner end of a recess 52 normally holds the reduced end 53 of the pin in a recess 54 in the hub of the handle 12. The casing has a key slot 55 and key stem guide 55' formed therein and theescntcheon plate 56 covers this slot and is riveted in place. The hole or recess 54 is so located relative to the groove 45 and side opening that the pin 46 engages in said hole when the number wheels have been reset to zero. The escutcheon plate has a safety block 57 formed integral therewith or attached thereto, which prevents picking the look and compels the use of a key whose bit shank can turn between the inner end-0f said block and the locking pin.

The flat spring do s 20 and 26-are slightly curved as initially ormed, as such formation results in less breakage and makes assembling of the parts easier.

A mounting plate 58 is adapted to be secured to either the bottom or rear side of the casing bysuitable screws engaging in rapped holes in the casing provided during its manufacture.

I desire it to be understood that this in- 'said wheels to zero on the turnin form or arrangement of parts except in S0 far as such limitations are specified in the handle on said shaft, a key-controlled lock-' ing pin mounted in said casing and in looking enga ement with said handle to lock said she against resetting and against movement during registering.

In testimony whereof, I aflix my signature.
